Hi all, complex problem here, and probably has a simple solution. I have a site connected to an MPLS network, a single T1, and a wireless connection, 2 routers, for the CPE, and one PE. The trick here is to route all 10.x.x.x addresses over the T1, and all internet traffic over the wireless. Simple enough with static routes, but the circuits need to back each other up. Using BGP I can prefer one circuit for the 10.0.0.0 and static the default, but how do I backup the default to use the other circuit when the default connection is down. Or reverse it, BGP the default, and static the 10.0.0.0/8. If the T1 goes down I want the traffic to fail over to the wireless automatically. If the Wireless goes down, I want the default to use the T1. The latter I can get to work, but the T1 failure, since static, I am having troubles with. How can I setup a weighted static to use the other router if the T1 fails? Or how can I setup BGP to prefer the t1 over the wireless, unless it drops?
Well 2 hours of programming and I got it to work using a combination of iBGP, eBGP and Weighted Static routing, and failover actually works as I planned. The problem that took the longest was each router was preferring itself for default until I added a weight to the i neighbor and bingo, that did it.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
